I just saw this article on Dutch news and it raised more questions than that it answered so I looked it up:

Apparently, a group of divers got into trouble due to quickly worsening weatherconditions. Four divers got to shore by themselves, but one of them (a Dutchman) died later. The others were saved by the authorities.
I dove there last year. Several sites in one place and one of the most popular divesites on the island.
My condoleances to family and loved ones.
